PRESS.

Application led March 29, 1912, Serial No. 687,223.

To all whom t may concern.'

Be it known that I, ELISHA H. ALvoRD, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State ofA VVashington,

have invented certain new and useful Improvements 1n Presses, of which the following 1s a specification.

My invention relates to presses, being tions of parts on which I desire protection,

succinctly defined in my annexed.- claims.

Referring to the accompanying drawings wherein like numerals of reference'indicate like parts throughout: Figure 1 is a top plan, with portions of one of the tension devices broken away. Fig. 2 is an end ele? vation in partial vertical section. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a vertical section taken on line 4 4 of Fig. l, parts being broken away, and Fig.

5 1s a fragmentary vertical section'illustrat! ing the contracted discharge throat and the main presser members.

Referring t0 the drawings by numerals of reference, 1 and l indicate perforated or foraminous presser members supported for movement to press and simultaneously advance the material to a discharge throat, comprising opposing laterally adjustable side wall sections 2, which wall .sections serve as auxiliary presser members tending to further press or to hold the material in its pressed condition, to thereby prevent. it from absorbing moisture from the interior of the rolls or from the superimposed body of material being fed.

Presser members 1, 1, which inthe present embodiment of my invention are'in the form of rolls, each comprises 'a cylindrical peripheral section supported at spaced points throughout its length on 1nternal annular members 6, to the outer of which said peripheral section is conven- Specification of Letters Patent.

Patented Aug. 8, 1916. Renewed November 1, 1915. Serial No. 59,150.

iently fixed, as' by screws 7 Annular members 6 are rigidly carried by suitable arms, fixed to a shaft 5, as shown. Presser members 1, 1 have their shafts 5 journaled in suitable stands 3 and 4 respectively, the latter of which is slidably supported on the supporting-frame 8 for movement toward and from the other. For yieldingly holding stand 4 against movement from stand 3, I provide tension devices, now to be described.

Reference numeral 9 indicates superimposed rods provided in like arrangement at each end of presser members l, 1 and each being Xed to a respective one of the stands 3 and 4, as by having screw threaded engagement in an internally threaded lugl thereof and provided on lts projecting portion witha lock nut 13, and having its opposite or free end portion projecting through and slidably guided in a lug 9 of the opposite stand. On the free projecting end portions of rods 9, springs 10 are arranged and confined between nuts l1 and the adjacent lugs 9.

In slidably mounting stand 4, I provide frame 8 with a wear strip or track 14 on which said stand is held for limited movement by bolts 15 which project upwardly through base slots 15 thereof (see Fig. 3).

Throat wall sections 2 which have their upper end portions directed from one another and preferably engaging the presser members l, l to clear the same of clinging material, extend downwardly in diverging paths which are eccentric with respect to the adjacent presser members and are then curved upwardly at the outer sides of said members to provide in conjunction with sections 2 moisture receiving chambers or pans 16, which areprovided with suitable end walls 16 and inclined downwardly toward one end portion, having an outlet 17.

Moisture receiving chambers or pans 1G are adjustably carried by screws 30, on swingingly supported carriers consisting of levers 18 fulcrumed on the endportions of shafts 5, the said screws having threaded engagement in the lower lend portions of said levers and swiveled in lugs 31 of the pans, by which construction the pans can be adjusted toward and from one another on the said levers, through rotation of the screws which can be effected in any desired manner.

Reference numeral 19 indicates slides mounted for sliding on rods 9 and connected by links 20 each with a pivot lug 18 of a respective lever 18. The movement of slides 19 is limited by shoulders 21, 21 between the latter of which and the adjacent slides, springs 22 are interposed.

Reference numeral 23 indicates a drive pulley fixed to one of, the shafts 5 and 2-11 indicates meshing gears fixed to the shafts 5 through which latter the presser members 1, 1 are driven in unison, the teeth of said gears 211 being of suitable depth to remain in mesh during bodily adjustment of presser member 1.

In practice, the material is fed between the presser members 1, 1 from their upper sides and as delivered from their lower sides encounters and is fixed between throat members 2, the said presser members 1, 1 and throat members 2 yielding outwardly independently of one another during this operation, as will be apparent. Moisture extractedfrom the material through the action of presser members 1, 1 passes into the latter through the apertures in the peripheral portions thereof and finally discharges from their lower side portions into chambers or pans 16.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of America, is

1. A press comprising opposing presser members supported in opposing relation for movement, means for simultaneously moving said presser members to thereby press and advance the material in the direction of its delivery movement, and an expansible discharge throat for the material arranged at the delivery side of said members to receive the pressed material from the latter and be expanded by said material.

2. A press comprising an eXpansible discharge throat yieldingly held against eX- pansio-n, presser members for simultaneously pressing and advancing material through said throat, one of said presser members being supported for movement from the other, and means yieldingly holding said last named presser member against movement from the other.

3. A press comprising a discharge throat having a laterally movable yieldingly held side wall section, opposing rotatable members for advancing material through said throat, and means for rotating said members.

4. A press comprising a discharge throat having a laterally movable yieldingly held side wall section, opposing rotatable members for pressing and advancing material through said throat, one of said members being supported for movement from the other', means yieldingly holding said last named member against movement from the other, and means for rotating said members.

5. A press comprising a discharge throat having side wall sections yieldingly supported for movement toward and from one another, a rotatable presser member, another presser member associated with said rotatable member for simultaneously pressing and advancing `material to said throat for passage therethrough, and means yieldingly pressing one of said presser members toward the other.
